Lena Dunham slammed critics who accused her of sexually molesting her younger sister, calling the public outcry ridiculous.

The sexual abuse allegations came after Dunham wrote the following shocking account in her explosive tell-all book, Not That Kind of Girl:

“One day, as I sat in our driveway in Long Island playing with blocks and buckets, my curiosity got the best of me. Grace was sitting up, babbling and smiling, and I leaned down between her legs and carefully spread open her vagina. She didn’t resist and when I saw what was inside I shrieked.”

“My mother didn’t bother asking why I had opened Grace’s vagina. This was within the spectrum of things I did. She just on her knees and looked for herself. It quickly became apparent that Grace had stuffed six or seven pebbles in there. My mother removed them patiently while Grace cackled, thrilled that her prank had been a success.”

Shortly after people accused Lena of sexually molesting her sister, she responded on Twitter: “The right wing news story that I molested my little sister isn’t just LOL – it’s really f**kng upsetting and disgusting.

“Usually this is stuff I can ignore but don’t demean sufferers, don’t twist words. I told a story about being a weird seven-year-old. I bet you have some to.”

Lena, who won a Golden Globe in 2013 for writing, directing and acting in her hit HBO series, Girls, also reveals her eating disorders, her past as a victim of sexual abuse and her ongoing battles with obsessive-compulsive disorder in a way that’s almost uncomfortable for the reader.

Of her eating disorder, Dunham writes:

“My food intake was a hard thing to share publicly. A lot of my life and work is sort of about not succumbing to [those pressures], so it’s a little painful to go, ‘Oh but look, there was a time where this dominated every moment of every day.’

In the hospital with crazy stomach pains. It was basically revealed that I’d been just drinking laxative tea and coffee and smoking cigarettes and then eating weird foods at weird hours. I really messed myself up.”

Not That Kind of Girl is an in-your-face lesson in oversharing and offers shockingly candid insights into the mind of one of today’s most talented young stars.
